Verified step by step guidance1
Understand the definition of a mixture: A mixture is a combination of two or more substances where each substance retains its own chemical identity and properties.
Recall that mixtures can be separated by physical means because their components are not chemically bonded; this is a key characteristic distinguishing mixtures from compounds.
Recognize that a mixture does not have a fixed composition throughout; the proportions of components can vary, unlike pure substances.
Note that a mixture does not consist of only one type of atom, as it contains multiple substances or components.
Conclude that the property 'Its components can be separated by physical means' best describes a mixture.
